The Intel Core i5-14400 is a desktop processor with 10 cores, launched in January 2024, at an MSRP of $221. It is part of the Core i5 lineup, using the Raptor Lake Refresh architecture with Socket 1700. Intel Hyper-Threading technology is available and effectly doubles the core-count of the P-Cores, to a total of 16 threads. Core i5-14400 has 20 MB of L3 cache and operates at 2.5 GHz by default, but can boost up to 4.7 GHz, depending on the workload. Intel is building the Core i5-14400 on a 10 nm production process, the transistor count is unknown. The multiplier is locked on Core i5-14400, which limits its overclocking capabilities.
With a TDP of 65 W, the Core i5-14400 consumes typical power levels for a modern PC. Intel’s processor supports DDR4 and DDR5 memory with a dual-channel interface. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the machine, Core i5-14400 uses a PCI-Express Gen 5 connection. This processor features the UHD Graphics 730 integrated graphics solution. Inside the box you will not only find the processor, but also a Laminar RM1 cooler.
Hardware virtualization is available on the Core i5-14400, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel is including the newer AVX2 standard, too, but not AVX-512.
